Matt Warman: I thank the right hon. Gentleman for his contribution to the debate. He has talked so much about my impermanence that I felt lucky to come back today, never mind any time in the future. He makes a reasonable point, with which I broadly sympathise. As this is a broad grouping that covers clauses 15 and 16  and the amendments to clauses 15, 16 and 17, I will discuss the policy intention behind the clauses in sequence, and address the amendments.
As the right hon. Gentleman said, it is obviously an opportune moment to pay tribute to the heroic work of our national security services. The Bill emphasises the importance of their advice, and it empowers the Government to manage the presence of high-risk vendors in our networks. The report to which he refers is important, but it is also important to say that it was published, as he said, in 2013. It related almost entirely to events that took place under Labour, and it predates the existence of the National Cyber Security Centre, so we are dealing to some extent with a different world. I will go into a bit of detail on that.
As the right hon. Gentleman knows, the Government announced in January last year that new restrictions should be placed on the use of high-risk vendors in the UK’s 5G and full-fibre networks. In July 2010, the Government worked with the NCSC to update the guidance following action taken by the US Government in relation to Huawei. Clauses 15 to 17 provide the principal powers that the Government need to manage the risks posed by high-risk vendors. Without such powers, the guidance issued to industry will remain unenforceable and therefore present a risk to national security.
